Add the ability to configure these registers in order to get the PHY to function on boards that need it. Because PHYs are auto-detected based on MDIO device IDs, allow PHY configuration to be specified in the parent Ethernet device node if no PHY device node is present.

phy/micrel: move flag handling to function for common use 2013-03-12T10:50:59+00:00 Hector Palacios hector.palacios@digi.com 2013-03-10T22:50:03+00:00 b6bb4dfcb1803765e7d12a9807a8d4650545199a The flag MICREL_PHY_50MHZ_CLK is not of exclusive use of KSZ8051 model. At least KSZ8021 and KSZ8031 models also use it. This patch moves the handling of this and future flags to a separate function so that the different PHY models can call it on their init function, if needed.
